The Ashtamangala () is the sacred set of Eight Auspicious Signs (, bājíxiáng) featured in a number of Indian religions such as Hinduism, Jainism, and Buddhism. The symbols or "symbolic attributes" () are yidam and teaching tools. Not only do these attributes (or energetic signatures) point to qualities of enlightened mindstream, but they are the investiture that ornaments these enlightened "qualities" (Sanskrit: guṇa; ). Many cultural enumerations and variations of the Ashtamangala are extant.
